This ensures reliability, scalability and performance of the Spark application.

The example performance monitoring system for such a involved system must Have the following features:

The monitoring system should provide granular visibility about each component inside cluster. They should able to accept circumstantial metrics about CPU, Memory, Storage, Disk I/O for local file and HDFS, stack traces etc. These metrics assist to quickly troubleshoot the faulty instances.

The monitoring system should provide code smooth metrics for applications (e.g. execution time, arguments used by different methods) running on spark. This will assist to identify gradual running methods, disk hot-spotting etc.

The monitoring system should store metrics for every second and allow us to analyse metrics by navigating across different time periods. They should able to execute second and sub second smooth dissection of these data. They should able to control the data retention epoch and easily access and analyse the past data when needed. This helps in analysing the current trend and predicting the future trend.

The monitoring system should provide an efficacious way of extracting meaningful information from a great volume of metrics being collected continuously. This includes querying of data using SQL or API, filtering of data, aggregation of values and applying custom analysis. This helps in smooth transformation and faster analysis of data.

The monitoring system should provide smooth access of information deduced from the analysis of metric data. There should be the option to display data in dashboard using different forms dote charts, graphs tables, etc. There should be the option to categorise the data based on host, time or job, and users should be able to further drill them down to corelate the different data points. There should be a provision for configuring alerts and notifications for user defined thresholds on metrics data. This helps DevOps teams and other stockholders of an organisation to accept the desired set of information quickly when it is needed.

In this article, we’ll develop a performance monitoring system using opensource tools & technologies. The spark application performance monitoring system is designed with three objectives:

Collect the performance metrics of system (driver & executors) and application code

Generate reports from metrics data in the configuration of graphs and charts

Apache Spark provides a web-ui and relaxation API for metrics. Spark also provides a variety of sinks including Consoles, JMX, Servlet, Graphite etc. There are few other open source performance monitoring tools available dote dr-elephant, sparklint, prometheus, etc. Metrics provided by these tools are mostly server smooth metrics, and few of them also provide information of running applications.

Uber JVM Profiler collects both server smooth and application code metrics. This profiler can collect replete metrics (cpu, memory, buffer-pool etc) from the driver, executor or any JVM. It can instrument existing code without modifying it, so it can collect metrics about methods, arguments and execution time. For storing metrics for timeseries analysis, they will utilize InfluxDB, which is a powerful timeseries database. They will extend Uber JVM Profiler and add a fresh reporter for InfluxDB so metrics data can be stored using HTTP API. For the dashboard of graphs and charts they will utilize Grafana, which will query the InfluxDB for metrics data.

Below are the details about tools/technologies used for the spark application performance monitoring system.

Uber JVM Profiler

Uber JVM Profiler is a distributed profiler which collects performance metrics and resource utilisation metrics from different nodes across the cluster. This JVM Profiler runs as a Java Agent along with the application and collects the different metrics. It publishes these metrics to a designated reporter for further analysis and reporting. Uber JVM Profiler was developed for profiling spark applications, but this can be used for profiling any JVM based application. There are three main components of Uber JVM Profiler:

Profiler: Uber JVM Profiler comes with the following built in profilers:

Transformer: This is a Class File Transformer to instrument java routine bytecodes. This transformer is used to instrument methods from MethodDuration and MethodArgument profilers.

Reporter: The following reporters are available:

KafkaOutputReporter – To forward performance metrics to Kafka topic.

FileOutputReporter – To write metrics in a file.

ConsoleOutputReporter – Sends metrics to console.

RedisOutputReporter – Store metrics to Redis database.

For more details about JVM profiler gratify advert to Uber’s blog post.

InfluxDB and Grafana

InfluxDB: InfluxDB is an open source time succession database which is designed for efficiently storing and querying a great amount of time-stamped data. This data could be IoT sensor data, real-time analytics data, application metrics data or dev-ops monitoring data. It provides automatic data lifecycle management by expiring & deleting traditional data. It provides write and query capabilities using SQL-like query language, HTTP API and client libraries. Check out the details here.

Grafana: Grafana is an open source metric dashboard and graph editor. Grafana also supports alerts and notifications for metrics. It supports many data sources dote Graphite, InfluxDB, OpenTSDB, Prometheus, Elasticsearch and CloudWatch. Many Dashboard and Plugins (both opensource and commercial) are available at Grafana’s website. For more details about Grafana visit the website.

System Architecture

Spark application runs on cluster network which may consist of a few nodes to thousands of nodes. For collecting metrics from this distributed system and sending the metrics to other systems for further analysis, they need a loosely coupled and vice tolerant architecture. Publishing the metrics to Kafka topic is one of the best solutions. Uber JVM profiler comes with a “KafkaOutputReporter” which can be used for this purpose. Another solution approach for storing and reading the metrics is by using the InfluxDB. InfluxDB provides HTTP API which can be used to query and write to database. This API supports both basic and JWT token authentication and URLS can be configured for HTTPS access. “InfluxDBOutputReporter” that they are discussing in this article invokes Write HTTP Endpoint to store the metrics collected by different profilers. Grafana provides a flush data source plugin for InfluxDB. Grafana uses Query HTTP Endpoint to fetch metrics data from InfluxDB and it displays the data on the dashboard in the configuration of flush graphs and tables. These graphs and tables are auto refreshed at fixed intervals, and time intervals can be configured in Grafana settings.

The architecture diagram of the performance monitoring system for spark application using Uber JVM Profiler, InfluxDB and Grafana is illustrated in figure 1 below.

Technologies and Tools

The following Table shows the technologies and tools used for a performance monitoring system.

Please advert to the documentation for installing and configuring these tools.

Design and Implementation

The following sections provide design and implementation details for a performance monitoring system for spark application. Uber JVM profiler collects metrics from driver and executors and these metrics Have circumstantial information dote role (driver/executor), processUuid and host. These details are useful for identifying the different systems and analysing their metrics. In InfluxDB they can utilize these details to query performance metrics of different executors. They can add processUuid in InfluxDb tags, so query performance will be high. First, they will create “metrics” database in InfluxDB, then they will add an “InfluxDBOutputReporter” in JVM Profiler code base, and finally they will configure the Grafana dashboard and graphs.

Create Metrics Database in InfluxDB

Start the InfluxDB server, which by default runs on 8086 port. For example, in Ubuntu system open a terminal and execute “influxd” command.

/user/bin$ sudo influxd

Once the server is up and running, start “influx” utility in another terminal. And then execute command to create “metrics” database.

/user/bin$ sudo influx

CREATE DATABASE metrics

Implement InfluxDBOutputReporter

We will implement “InfluxDBOutputReporter” in JVM-Profile code base. advert to the InfluxDBOutputReporter.java file at “influxdb_reporter” fork at GitHub for the implementation details discussed in this section.

We will utilize influxdb-java library to interact with InfluxDB database server. It uses HTTP API to read and write in the InfluxDB database. Update the pom.xml file and add maven dependency for influxdb-java library.

InfluxDBOutputReporter class needs to implement com.uber.profiling.Reporter interface. They need to override public void report(String profilerName, Map<String, Object> metrics) routine and public void close() method. The “profilerName” will be the measurement cognomen in “metrics” database.

As InfluxDB uses Line Protocol to store key=value pairs, they need to process metrics data available in Map<String, Object> sent by Profiler and metamorphose them to a configuration so that it can be stored in a Point of single series. They can utilize the value of “name” property from metrics, if it is available, to configuration the cognomen of field. If “name” property is not available, then they can utilize a counter value. InfluxDB supports regular expression for domain cognomen in query, so querying these fields won’t be an issue.

Create Point and Batchpoint using influxdb-java library APIs and write the Batchpoints to InfuxDB database.

For reading database connection properties from the yaml file they Have to utilize com.uber.profiling.YamlConfigProvider and com.uber.profiling.Argument classes. Add a reference of InfluxDBOutputReporter class in dispute class and invoke setProperties routine to pass properties coming from yaml file. A sample yaml file for influxdb is available at resources/influxdb.yaml at GitHub.

Add Data Source and Dashboard in Grafana

This section provides brief details on the steps needed for adding a graph for metric data from InfluxDB in Grafana. gratify check on the Grafana documents for in-depth details:

Start the Grafana server. On Ubuntu they can execute the below command. By default, it runs on port number 3000.

sudo service grafana-server start

Open http://localhost:3000/ in a browser and create data source for InfluxDB. Add cognomen as “InfluxDBDataSource”, sort as “InfluxDB”, default URL for InfluxDB is “http://localhost:8086” and Database cognomen will be “metrics”.

Create a fresh dashboard by clicking on Graph, click Edit and add query for graph. Below is a sample query for InfluxDB database.

select "heapMemoryCommitted" as Committed, "heapMemoryTotalUsed" as Used from "metrics"."autogen"."CpuAndMemory” where “role" = 'driver' AND time > now() – 5m

Grafana provides the option of defining template variables which can be passed in query. This will be useful for displaying data from multiple executors on dashboard. For example, they can create variables for “executorProcessUuid” & “timeInterval” and utilize them in query as below.

select "heapMemoryCommitted" as Committed, "heapMemoryTotalUsed" as Used from "metrics"."autogen"."CpuAndMemory” where "processUuid" =~ /^$executorProcessUuid$/ AND time > now() - $timeInterval

A sample Spark-Metrics-Dashboard JSON file has been provided at GitHub. This file can be imported at Grafana server. Open the URL http://localhost:3000/dashboard/import in a browser and click on “Upload.json File”.

Build and Deploy

This section describes the steps to build and deploy a performance monitoring system. Application code can be cloned from the “influxdb_reporter” fork at GitHub.

Use the below command to build the JVM profiler with “InfluxDBOutputReporter”.

mvn clean package

Copy the JVM Profiler-0.0.9.jar file created by maven build to some directory. (e.g /opt/profiler). They can champion influxdb.yaml file as well in this directory.

We will utilize the existing JavaNetworkWordCount application for profiling which is shipped with Apache Spark. Source code is available at /spark-2.3.1-bin-hadoop2.7/examples/src/main/java/org/apache/spark/examples/streaming.

To dash JavaNetworkWordCount application, they need to dash Netcat server using the below command.

nc -lk 9999

Go to /spark-2.3.1-bin-hadoop2.7/sbin and start the Master using the below command.

./start-master.sh

We can accept the master URL from log file. Pass this URL to command to start the Worker.

./start-slave.sh -c 2 spark://192.168.1.6:7077

Go to /spark-2.3.1-bin-hadoop2.7/bin and execute the below command. This command will execute JavaNetworkWordCount application and start the JVM profilers for driver and executor. Check the Uber JVM profiler GitHub readme page for details about the parameters.

We will accept the cognomen of “Measurements” created in “metrics” database as below.

CpuAndMemory

IO

ProcessInfo

Stacktrace

We can check the data populated in these Measurements. For example, they utilize the below command to fetch a single record from CpuAndMemory measurement.

select * from CpuAndMemory restrict 1

Go to Grafana dashboard for spark. Graphs for metrics should be populated with data. Below is the sample dashboard.

Figure 2. Sample Grafana dashboard for spark metrics

Pros and Cons

The performance monitoring system they discussed in this article collects different system and application metrics using Uber JVM Profiler and stores them in the InfluxDB time-series database. The time-series database provides data retention policies, continuous queries, springy time aggregations and efficient handling of millions of records both for live and batch processing. These timeseries data helps us to analyse how system changed in the past, how the system is behaving in the present and prognosticate how it may change in the future. They can identify the patterns of failures by correlating these metrics collected over time. They created a dashboard using Grafana which helps us in smooth access and navigation across different types of metrics. The DevOps team can utilize these graphs and charts to corelate the different metrics to understand the system behaviour and can identify hotspots in the data. This helps in maintaining the compliance and achieving the service smooth agreements of an application. Overall this performance monitoring system helps in achieving the Continuous Monitoring of the system.

The limitations of this performance monitoring system are in line with the limitations they Have for the agent-based profiler. The agent-based profiler may consume a certain amount of computing resources. Sometimes it may require troubleshooting and patching, which might be difficult for great geographically distributed system. You might need to complete the paper toil before installing the agents on the production system. They also Have to deem the security, scalability and availability of the performance monitoring system, i.e. monitor the monitoring system. Most of these challenges can be overcome by proper designing and tuning of the application and system. If you are not allowed to install profiler agents on a production system, then you can deem anagent-less system, but it has its own limitations, such as less granular metrics and increased network overload.

Summary

For involved spark applications identifying, debugging and resolving, the production issues are not smooth tasks and they need an efficacious performance monitoring system which can assist us with this. Uber JVM Profiler is a noteworthy addition to the open source community. This JVM Profiler can be extended and a fresh reporter for publishing metrics can be added. Performance metrics for spark applications collected by different profilers can be stored in InfluxDB. The “InfluxDBOutputReporter” that they discussed in this article uses HTTP API to write metrics for spark drivers and executors to InfluxDB. Grafana provides a plugin for InfluxDB and uses HTTP API for querying the metrics. They can create a dashboard with charts, tables and graphs for these metrics, which can be auto refreshed in fixed intervals. Code for “InfluxDBOutputReporter” is available here, and Spark-InfluxDB-Grafana.json file is available here.
